The other day I was playing with my pilot 09 and during the game, the screw that holds the spring and ball that locks the cocking pin in the rear of the bolt came out and I lost all those parts (except the pin). Does anybody know a replacement screw that will fit? I have tried emailing Spyder but I think they don't exist anymore.

It's a metric screw. Sorry, I don't remember much more than that, but you should be able to find a replacement set screw, ball bearing, and some spring you can cut a piece off of at a decent hardware store.

Strangely this happened to me too about two weeks ago. I was using the TechT bolt, and the set screw never really felt tight in it. Kingman tech support was very nice and shipped me replacements. The set screw they shipped me looks smaller than the original and fits much better. The bag said VS bolt set screw, so I guess its the same part in the electra, pilot, and VS bolts.
